Patent CA-2198733-A1 (CA)
Title: True zoom capability on a spot scanning electronic printer
Inventor: SHENK EDWIN K
IPC: B41J2/45
Filed: 1995-08-31
Abstract: A method and apparatus for producing a zoom system within a printer. The zoom system for enlarging or reducing an original image on a printed medium or adjusting aspect ratio of an image. The zoom system utilizing a phase lock loop to produce a pixel clock in a fast scan direction and governing motor control to alter incremental movement of the recording medium in the slow scan direction. Individual pixel size is then governed by varying a frequency of the pixel clock to alter a width of the pixel projected onto the recording medium and length of the pixel is governed by governing overlap of successive print lines and repeating print lines if necessary.
Patent CA-2201283-A1 (CA)
Title: Platelet blockade assay
Inventor: COLLER BARRY S
IPC: G01N33/86
Filed: 1995-09-20
Abstract: The present invention is an assay for determining glycoprotein IIb/IIIa receptor blockade in whole blood. Agglutinization of small polymeric beads coated with a glycoprotein IIb/IIIa ligand such as fibrinogen results when the beads are contacted with whole blood containing platelets with glycoprotein IIb/IIIa receptors that are not blocked. Failure to agglutinate indicates that blockade of the GPIIb/IIIa receptors has been achieved. In a preferred embodiment, the addition of a thrombin receptor activator results in an assay that is rapid and convenient enough to be performed at bedside and that results in agglutination of the small polymeric beads within a convenient, known period of time if the glycoprotein IIb/IIIa receptors are not blocked.

Patent CA-2211737-A1 (CA)
Title: Fluid distribution member for absorbent articles exhibiting high suction and high capacity
Inventor: NOEL JOHN RICHARD
IPC: D21H13/24
Filed: 1996-01-26
Abstract: The fluid distribution members according to the present invention preferably comprise three basic components: chemically stiffened, twisted, and curled bulking fibers, high surface area fibers, and thermoplastic binder fibers.  Fluid distribution members according to the present invention use a high surface fiber to provide capillary pressure (or suction) to the fluid distribution member. These high surface area fibers are generally small and highly conformable. They provide the substrate with capillary pressure well in excess of the capillary pressure found in the bulk-providing chemically stiffened, twisted, and curled fibers alone. A presently preferred fiber for this high surface application is the eucalyptus family of wood pulp fibers.  Eucalyptus provides the capillary pressure usually associated with cellulose fines, but at a large enough length and denier so as to not fill in the voids provided by the chemically stiffened, twisted, and curled fibers and will not easily pass through a forming screen.

Patent CA-2250994-A1 (CA)
Inventor: BECHERUCCI RAFFAELE
IPC: H02K7/04
Filed: 1998-10-21
Abstract: The balancing of rotors for dynamo-electric machines (e. g., electric motor armatures) is achieved by attaching a balancing strip to the rotor after an impregnation resin has been applied to the wire coils, and the unbalance of the rotor has been measured. To create the balancing strip, a material supply selectively and incrementally delivers a predetermined quantity of material, such that the quantity of material has a mass sufficient to compensate for the measured unbalance of the rotor. The predetermined quantity of material is separated from the material supply to form a balancing mass, and the balancing mass attached to the rotor to compensate for the measured unbalance. A mounting member having a recess may be preliminarily attached to the rotor for subsequent attachment of the balancing mass thereto. A second material supply may be provided such that a controller can select between the first and second material supplies.
